  • First Online:
Chirality, Magnetism and Magnetoelectricity

Part of the book series: Topics in Applied Physics ((TAP,volume 138))

Abstract

In this chapter, we review recent developments of two usages of topology in magnetism. One is to classify spin structures with different topological numbers (topology in real space). The other usage is to distinguish normal magnetic materials from those magnetic materials supporting topologically protected unidirectional surface spin waves inside spin wave band gaps (topology in reciprocal space).
